T aZZ whom it neay concern:

Be it known that I; WILLIAM ABERNETHY COWLES, alcitizen of the UnitedStates, re-

sidingat Ansonia, in the county-of New I Iaven, State of Connecticut,have invented a new and useful scouring-Machine, of which the followingis a true and exact specification.

My invention relates toa machine for scouring or cleaning copper platespreparatory to the tin'ning thereof.

I will describe a machine embodying my improvement, and then point outthe novel features in the claims. I

In the accompanying drawings, Figure 1-is a view in elevation, partly insection, of the.

0 section, of one of the securing machine. Fig. 2 is a top view thereof.5 Fig. 3 is an end elevation. Fig. 4 is a vertical transverse sectiontaken on the line A B' of Fig. 1; and Fig. 5 is a detail view, partly inor cleaning rollers. K K r K 1representsasuitablebed,havingmountedthereon the supporting standards 2 3, in which the feeding and scouringrolls, together with their driving mechanisnn. are carried. a.-

,4 and 5i'epresentlrolls which feed the plates to cleaning or scouringrolls 6 7, located in the rear of said feed-rolls. The scouring orcleaning rolls are preferably driven at amuch 0 greater speed than thefeed-rolls, and by this .isin engagement with a gear 15, carried-on 5Oshaft of the upper feed-roll.

arrangement I am enabled to hold the plates or sheets by thefeed-rollswhile they are being moved forward, so -that the scouring orsists of a .pulley 11, carried on a sleeve 12,

loosely journaled on oneend of shaft 8, said sleeve being provided witha pinion 14, which the shaft of the lower feed-roll. This shaft is alsoprovided with a similar pinion 16 in engagement with a pinion '17,carried on the 1 Located immediately in the rear o flthe feedroll is aspray-pipe 18, connected at one end with a pipelf), and at the other endof this pipe 19 is a second spray-pipe 20, located immediately in therear of the cleaning or scour ing rolls. WVaten is supplied to thesespraypipes through the pipe 20?.

21 represents a screen located over the feed.

and scouring or cleaning rolls to prevent the water being thrown off therolls by the centrifugal force. One end, is provided with a curvedportion 22 adjacent the spray pipe 20 for guiding the water from thespray-pipe to the cleaning or scouring rolls and also onto the sheetbeing scoured to give it a final washing. The water from the spray-pipe18 drops over the plate being cleaned and from the feed-rolls onto achute 23, from Where it is conducted away through a waterway locate inthefbed. The water from the spray-pipe after. flushing the plate isguided away by means of the chute 24. J

The feed-rolls may be conveniently covered with rubber to preventtheplate slipping, and the scouring-rolls are preferably provided with asomewhat-roughened surface, which is also absorbent, so that the dirtand particles clinging to-the plate may be loosened therefrom in orderthat they may be carried away by the water from the spray-pipe. Aconvenient way of forming these rolls is shown inlIig. 5, and consistsofa number of disks of canvas, which are held and clamped on the shaft ofthe rolls by means of the plates 25 and 26, and the clamp-nuts 27. Assoon as water is' supplied to these rollsthe'canvas disks swell, so thata hard and compact roll with a sufficiently rough abrading-surface isformed. It is obvious that any other mate-- rial than canvas may beemployed. Hence I do not care to limit myself to the use of canvas forthe rolls. v r

The operation of my machine is as follows:

The plates to be cleaned after being taken from the bath arefed to thefeed-rollers, which move them forward to the scouring-rollers at ICOsheets, which are carried away by the water from the spray-pipe 20. p

What I claim as my invention is;

1. In a scouring-machine,the combination with feed-rolls, the cleaningor. scouring rolls made of absorbent material, means forzl'otating saidrolls, and a water-supply for said feed and cleaning or scouring rolls.

'2. In a scouring-machine, the combination of the feed-rolls, thecleaning or scouring rolls, means for rotating said rolls, saidfeedrolls being each provided with a soft covering and said cleaning orscouring rolls being each.

formed from a number of fabric disks, and a water-supply for saidfeeding and cleaning or scouring rolls, substantially as described.

3. In a'scouring-machine, the combination with feed-rolls, cleaning orscouring rolls,

means for rotating said feed and cleaning or scouring rolls, awater-supply, and a branch rom said supply leading to each set of rollsfor supplying water to said rolls, one'of said branches extendingbetween the rolls so asto suppl water to-the material being cleaned,substantially asdescribed.

4:. In 'a scouring-machine, with feed-rolls, cleaning the combination rscouring rolls,

means foi rotating said fee and, cleaning or scouring rolls, awater-snpplyfor each set 05 ennui ABER'N'ETHY COWLES.
